HUMIDIFIER Application led November19, 1930. Serial No. 496,587.

My invention relates to improvements in humidifers, and the object of my improvements is to supply a device of this class adapted for humidifying theair in an inclosure quickly and effectively, and to maintain a suitable degree of humidity utherein according to hygienic necessities.

A particular improvement is the construction of absorbentL devices forliquid in the apparatus, such devices being assembled and unitarily supported in a manner rendering them easily removable together lfor renewals or for cleaning.

Other improvements will be hereinafter specically alluded to herein, and it is to be understood that modications mayl be effected in the apparatus variously Without therebydeparting from the protection of the claims or from the scope of this invention. In my apparatus, I have successfully reduced to practise the means which are here-- inafter described and claimed, and which are illustrated in the accompanying -drawings, in which Fig. 1 is a medial longitudinal vertlcal section of my humidifying appara? tus, with certain elements shown in side elevation. Fig. 2 isa rear elevation, and Fig. 3 a front elevation of the device. an end elevation of the absorbent liners as so-.unitarily assembled together in a single humidifying unit, with parts broken away Vin a vertical transverse section thereof. Fig. 5 is a top plan of the complete apparatus, with parts broken away, and showing the v3.5 hinged top closure in an open-position. Fig.

6 is a fragmentary horizontal section and with parts in top plan of portions of thehumidifying sheets and their supports with end connections, and on an enlarged scale.

The numeral 1 denotes a housing, with closed bottom and sides, -imperforate, but whose front and rear walls 3 and 5 respectively have in their upper portions relative# xly large like circular apertures 2, the front 5 opening 2 being preferably but not necessarily covered by a foraminous grating 4. The top of the housing has a large rectangular opening 9, closed by an arched cover 6 on hinges 7 and having near its freelongitu- 5 dinal edge a medial finger knobV 8.

Fig. 4 is Referring to said Figs. 1 and 2, the numeral 10 denotes an'electric motor at the rear of the housing 1 with its armature shaft 11 extending centrally through the rear Wall aperture 2, and supported on arms 14 se- 55 cured to the inner wall of the rear part 5 of the housing. On said shaft within the housing is a radially vaned fan 12 surrounded by a wire and open guard frame 13.

Removably mounted within the housing 1 60 is a multifold lining device, which may be inserted through or removed from the top opening 9 quickly and easily,`the fingers of the operator being protected by said grating 13 around the fan wheel 12, whether the lat- 55 ter is'or is not in rotation.

The constitutents of this lining device are similar but vary only in relative positions and sizes being nested concentrically in spaced relation, and composed each of one or more contacting layers or sheets 16 of absorbent material, such as blotting paper or the like, supported uponboth outer faces by reticulated wire netting-s 15 'which prevent them from collapsing When'wet and softened. As shown in Fig. 4, these liners 15' and 16 are arranged regularly as upright from their bottomedges and connected medially` by arched parts which are concentric, air passages thus beingleft throughout between theV 8 vliners from front to rear thereof, and with the arched parts preferably concentric also with the centrally alined motor vshaft 11.

-To rigidly connect and supp-ort the lower parts of these liners as an-unitary structure,

I haveemployedl the following means.l

Referring now to said Figs. 4, 5 and 6," and particularly to theenlarged detail shown in .'Fig. 6, the straight upright. end parts at front and rear of each liner combination 16 and 15 is'inclose'd `and clasped xedly by a channeled bar 19 soldered or,otherwise aiiixed thereto. Secondly, the lower parts of the channel bars- 19 are inclosed and the liners 16-and 15 held in fixed and spaced relation bv horizontal and rectangularly convoluted foot-bars 17 likewise soldered upon the channel bars 19. Finally, at each end of the united liners, a bottom transverse flat bar 18 is soldered upon and across the outer portions ras ` of the convoluted bars 17 Thus the whole structure is stif'ened and reinforced, and can be handled as an unitary construction.

As shown in said Fig. 5, each liner 15 and 5 16 has a top medially longitudinally positioned aperture 20 through which water or other suitable liquid may be poured through the liners without removing their aggregation from the housing 1, and preferably the apertures 20 are offset from each other in the alternated liners, so that when the liquid is poured therethrough, it is diverted lengthwise along the arched tops of the liners in a way which wets the tops of the liners initially, the liquid thence moving down the absorbing sheets 16 into the bottom of the housing which provides a tank in which the lower parts of the liners are immersed. Capillary attraction of the sheets 16 then keeps them wet until the liquid supply exhausts or is renewed as before.

The motor in action causes its rapidly rotating fan wheel 12 to drive a strong draft or air from the rear wall opening to the front inclosure. ably supported upon the top of a stand or other elevated construction in order to thereby set up air currents for equable air distribution.

When the liner assembly after a time has its absorbent sheets coated more or less with adherent impurities from the passing air drafts, the unitary assemblage may be rereturned to the device.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

tank part, means for driving an air current through it and out through its front wall tank art, sai liner' device consisting of an' assem lage of spaced absorbent sheets shaped and arranged respectively as concentric arches intermediate said opposite wall apertures and capable of conducting liquid from the tank part upwardly by capillary attraction, foraminous rigid sheathing for said sheets, and stepped rigiddevices mounted across the vlower end parts-of the sheets and Wall opening 2 and out into the room or other The apparatus may be removmoved as one body for cleansing, and then 1. 'A humidifier, comprising a housing 1 with apertured end walls above a bottom sheathing and secured to the latter to render the liner device a unitary structure.

3. A humidilier, comprising a housing with opposite wall apertures above a tank part, a liner device positioned within said housing removably and consisting of spaced upright absorbent materials, sheathing of reticulated material positioned upon opposite faces of each said materials to rigidly maintain its relative position, means for propelling air through the housing, and convoluted rigid end connections between the lower end parts of said sheathing and secured thereto to maintain the liner device as an unitary structure for traversing said top opening of the housing in entry or removal.

n testimony whereof I aiiX my signature.
